# RoundRectShape

`public class RoundRectShape`
`` `` `extends RectShape` ``

java.lang.Object
↳ | android.graphics.drawable.shapes.Shape
| ↳ | android.graphics.drawable.shapes.RectShape
|  | ↳ | android.graphics.drawable.shapes.RoundRectShape

Creates a rounded-corner rectangle. Optionally, an inset (rounded) rectangle can be included (to make a sort of "O" shape).

The rounded rectangle can be drawn to a Canvas with its own draw() method, but more graphical control is available if you instead pass the RoundRectShape to a `ShapeDrawable`.

## Public constructors

### RoundRectShape

    public RoundRectShape (float[] outerRadii,
                    RectF inset,
                    float[] innerRadii)

RoundRectShape constructor.

Specifies an outer (round)rect and an optional inner (round)rect.

Parameters
`outerRadii` | `float`: An array of 8 radius values, for the outer roundrect. The first two floats are for the top-left corner (remaining pairs correspond clockwise). For no rounded corners on the outer rectangle, pass `null`. This value may be `null`.
`inset` | `RectF`: A RectF that specifies the distance from the inner rect to each side of the outer rect. For no inner, pass `null`. This value may be `null`.
`innerRadii` | `float`: An array of 8 radius values, for the inner roundrect. The first two floats are for the top-left corner (remaining pairs correspond clockwise). For no rounded corners on the inner rectangle, pass `null`. If inset parameter is `null`, this parameter is ignored. This value may be `null`.

## Public methods

### clone

    public RoundRectShape clone ()

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object `x`, the expression:

>      x.clone() != x

will be true, and that the expression:

>      x.clone().getClass() == x.getClass()

will be `true`, but these are not absolute requirements. While it is typically the case that:

>      x.clone().equals(x)

will be `true`, this is not an absolute requirement.

By convention, the returned object should be obtained by calling `super.clone`. If a class and all of its superclasses (except `Object`) obey this convention, it will be the case that `x.clone().getClass() == x.getClass()`.

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by `super.clone` before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by `super.clone` need to be modified.

The method `clone` for class `Object` performs a specific cloning operation. First, if the class of this object does not implement the interface `Cloneable`, then a `CloneNotSupportedException` is thrown. Note that all arrays are considered to implement the interface `Cloneable` and that the return type of the `clone` method of an array type `T[]` is `T[]` where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class `Object` does not itself implement the interface `Cloneable`, so calling the `clone` method on an object whose class is `Object` will result in throwing an exception at run time.

Returns
`RoundRectShape` | a clone of this instance.

Throws
`CloneNotSupportedException` |

### draw

    public void draw (Canvas canvas,
                    Paint paint)

Draws this shape into the provided Canvas, with the provided Paint.

Before calling this, you must call `resize(float, float)`.

Parameters
`canvas` | `Canvas`: the Canvas within which this shape should be drawn
`paint` | `Paint`: the Paint object that defines this shape's characteristics

### equals

    public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

Parameters
`o` | `Object`: the reference object with which to compare.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### getOutline

    public void getOutline (Outline outline)

Computes the Outline of the shape and return it in the supplied Outline parameter. The default implementation does nothing and `outline` is not changed.

Parameters
`outline` | `Outline`: the Outline to be populated with the result. Must be non-`null`. This value cannot be `null`.

### hashCode

    public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the `equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

## Protected methods

### onResize

    protected void onResize (float w,
                    float h)

Callback method called when `resize(float, float)` is executed.

Parameters
`w` | `float`: the new width of the Shape
`h` | `float`: the new height of the Shape
